Series LUE-LUD

GAL has developed an entirely
innovative type of louvre, Series LUE / LUE-F and LUD, that sets
standards for the future. It is suitable for both architectural
and industrial applications.

The novel design of the aerodynamically optimised blade profiles
was developed on the basis of an aircraft wing profile and tested
at the German Aerospace Centre (DLR) in Göttingen. It enables
maximum air intake capacity and optimum rain-tightness.

The coefficient of discharge Cv0 of 0.43 with a rain-tight
position of 45° speaks for itself. This new louvre model with
stormproof blades is still effective when installed in highly exposed
locations where high wind speeds can occur.

The louvres can be individually adapted to match the architecture
or colour of the building facade.

Design:

Series LUE-F - the fixed blade version, is suitable for large-scale
air supply systems due to its extremely favourable aerodynamic
properties and its excellent rain-tightness.

Series LUE-R, the operable version,
can be fitted with the optional extra of integrated lip seals
on the blade profile and with side frame block seals (special
aluminium profile with inserted brush seal) to minimise leakage
losses.

Series LUD-R - the double-skin, operable
version has blades made of hollow extruded aluminium. This increases
torsional rigidity and static load capacity, and enables the attainment
of large span widths.

Series LUD-A, the double-skin, operable
version, has a sound absorbing lining.
